A wind turbine is a device that converts the kinetic energy of wind into electrical energy. As of 2020, hundreds of thousands of large turbines, in installations known as wind farms, were generating over 650 gigawatts of power, with 60 GW added each year. [1]
Some wind turbines on public display go one further, with observation decks beneath their nacelles. The observation decks are accessed with stairs inside the tower. Austria. Wind turbine at Pesendorf, Lichtenegg, Lower Austria. Type Enercon E-66 [17] One turbine at the wind farm Energiepark near Bruck an der Leitha, Type Enercon E-66; Canada
Wind turbine design is the process of defining the form and specifications of a wind turbine to extract energy from the wind. [181] A wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power , and other systems to start ...
The MOD-2 wind turbine cluster of three turbines produced 7.5 megawatts of power in 1981. In 1987, the MOD-5B was the largest single wind turbine operating in the world with a rotor diameter of nearly 100 meters and a rated power of 3.2 megawatts. It demonstrated an availability of 95 percent, an unparalleled level for a new first-unit wind ...
Wind turbines have some of the lowest global warming potential per unit of electricity generated: far less greenhouse gas is emitted than for the average unit of electricity, so wind power helps limit climate change. [118] Wind power consumes no fuel, and emits no air pollution, unlike fossil fuel power sources. The energy consumed to ...
This list also includes the most powerful onshore wind turbines, although they are relatively small compared to the largest offshore ones. As of June 2024, the most powerful wind turbine in operation is the world's first 18MW semi-direct drive offshore wind turbine, developed by Dongfang Electric Corporation. [1] In October 2024, Dongfang ...

Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with wind turbines, generally grouped into wind farms and connected to the electrical grid.
